Abstract

A vehicle window opening and closing control device has a driver seat unit that is provided in a driver seat of a vehicle, and a sub-switch that is provided in a seat other than the driver seat. The driver seat unit includes a main switch that operates opening and closing of a first window of the driver seat and a second window of the seat other than the driver seat and a controller that controls a driver seat motor provided in the driver seat and an other-seat motor provided in the seat other than the driver seat to perform manual opening and closing and automatic opening and closing of the first and second windows based on the operation of the main switch. The sub-switch is a switch that performs only the manual opening and closing of the second window using the other-seat motor.

First claim

What is claimed is:

1. A vehicle window opening and closing control device comprising:
a driver seat unit that is provided in a driver seat of a vehicle; and
a sub-switch that is provided in a seat other than the driver seat,
wherein the driver seat unit includes a first main switch that operates opening and closing of a first window of the driver seat, a second main switch that operates opening and closing of a second window of the seat other than the driver seal and a controller that controls a driver seat motor provided in the driver seat and an other-seat motor provided in the seat other than the driver seat to perform manual opening and closing and automatic opening and closing of the first and second windows of all seats comprising the driver seat and the seat other than the driver seat based on the operation of the first and second main switches,
wherein the sub-switch is a switch that performs only the manual opening and closing of the second window using the other-seat motor,
wherein the first main switch and the second main switch are connected to the controller,
wherein the controller and the driver seat motor are connected to each other by first and second wirings without the first main switch intervening therebetween, and a direction of a current passed through the driver seat motor and the first and second
wirings switches according to the opening and closing operation of the first window using the first main switch,
wherein the controller and the other-seat motor of the seat other than the driver seat are connected to each other by third and fourth wirings through the sub- switch of the seat other than the driver seat without the second main switch intervening therebetween, and a direction of a current passed through the other-seat motor, the third and fourth wirings, and the sub-switch switches according to the opening and closing operation of the second window using the second main switch, and
wherein the controller comprises a catch detector that detects generation of a catch in the first and second windows, and monitors the currents of the driver seat motor and the other-seat motor passed through the first to fourth wirings, and detects generation of catch in the windows of the driver seat and the seat other than the driver seat based on states of the currents detected by the catch detector.

2. The vehicle window opening and closing control device according to claim 1 ,
wherein the controller detects a ripple generated in each of the currents passed through the first to fourth wirings, and determines an opening and closing positions of the first and second windows from the states of the ripples.

3. The vehicle window opening and closing control device according to claim 1 ,
wherein, when the opening and closing operation of the second window is performed using the second main switch while the opening and closing operation of the second window is also performed using the sub-switch, and when the window opening and closing operations are performed in an identical direction using the second main switch and the sub-switch, the controller rotates the other-seat motor such that the second window is opened or closed in the direction.

4. The vehicle window opening and closing control device according to claims 1 ,
wherein, when the opening and closing operation of the second window is performed using the second main switch while the opening and closing operation of the second window is also performed using the sub-switch, and when the window opening and closing operations are performed in opposite directions to each other using the second main switch and the sub-switch, the controller stops the other-seat motor.

5. The vehicle window opening and closing control device according to claim 1 ,
wherein the sub-switch and the other-seat motor are provided in each seat.

6. The vehicle window opening and closing control device according to claim 2 ,
wherein the sub-switch and the other-seat motor are provided in each seat.

7. The vehicle window opening and closing control device according to claim 3 ,
wherein the sub-switch and the other-seat motor are provided in each seat.

8. The vehicle window opening and closing control device according to claim 4 ,
wherein, when the manual opening operation of the second window is performed using the second main switch while the manual closing operation of the second window is performed using the sub-switch, or when the manual closing operation of the second window is performed using the main switch while the manual opening operation of the second window is performed using the sub-switch, the controller stops the other-seat motor while both the main switch and the sub-switch are operated, and the controller rotates the other-seat motor according to the operation of one of the switches when the operation of other switch is stopped.

9. The vehicle window opening and closing control device according to claim 8 ,
wherein the sub-switch and the other-seat motor are provided in each seat.

10. The vehicle window opening and closing control device according to claim 4 ,
wherein the sub-switch and the other-seat motor are provided in each seat.

11. The vehicle window opening and closing control device according to claim 4 ,
wherein, when the automatic opening operation of the second window is performed using the second main switch while the manual closing operation of the second window is performed using the sub-switch, or when the automatic closing operation of the second window is performed using the second main switch while the manual opening operation of the second window is performed using the sub-switch, the controller determines that the catch is generated in the second window by the stop of the other-seat motor, and the controller stops automatic opening action or automatic closing action of the second window.

12. The vehicle window opening and closing control device according to claim 11 ,
wherein the controller performs manual opening action or manual closing action of the second window according to the operation of the sub-switch after stopping the automatic opening action or the automatic closing action of the second window.

13. The vehicle window opening and closing control device according to claim 12 ,
wherein the sub-switch and the other-seat motor are provided in each seat.

14. The vehicle window opening and closing control device according to claim 11 ,
wherein the sub-switch and the other-seat motor are provided in each seat.

15. A vehicle window opening and closing control device comprising:
a driver seat unit that is provided in a driver seat of a vehicle; and
a sub-switch that is provided in a seat other than the driver seat,
wherein the driver seat unit includes a main switch that operates opening and closing of a first window of the driver seat and a second window of the seat other than the driver seat, and a controller that controls a driver seat motor provided in the driver seat and an other-seat motor provided in the seat other than the driver seat to perform manual opening and closing and automatic opening and closing of the first and second windows based on the operation of the main switch,
wherein the sub-switch is a switch that performs only the manual opening and closing of the second window using the other-seat motor,
wherein the driver seat unit and the driver seat motor are connected to each other by first and second wirings, and a direction of a current passed through the driver seat motor and the first and second wirings switches according to the opening and closing operation of the first window using the main
